Compiler Usage
When first introduced in 2000, SSE2 was not supported by software development tools. For example, to use SSE2 in a Microsoft Developer Studio project, the programmer had to either manually write inline-assembly or import object-code from an external source. Later the Visual C++ Processor Pack added SSE2 support to Visual C++ and MASM.
The Intel C++ Compiler can automatically generate SSE4/SSSE3/SSE3/SSE2 and/or SSE-code without the use of hand-coded assembly.
Since GCC 3, GCC can automatically generate SSE/SSE2 scalar code when the target supports those instructions. Automatic vectorization for SSE/SSE2 has been added since GCC 4.
The Sun Studio Compiler Suite can also generate SSE2 instructions when the compiler flag -xvector=simd is used.

Famous quotes containing the word usage:
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
